Gestures substituting for a 'taboo' word?

[positive pcr]

In a National Public Radio story from 18 Jan 2003, 'Cuba Confidential' Looks
at Castro and the Future,
(discover.npr.org/features/feature.jhtml?wfId=926210)
NPR's Tom Gjelten reports that some Cubans use a hand movement (of tugging
at the chin simulating a beard) to avoid using Fidel Castro's name when
talking about him. Are there other common examples where certain "taboo"
words are replaced with non-spoken gestures? Religious examples? Political
examples?
